Manganflurlite is a rare phosphate mineral typically found in complex granite pegmatites as a product of secondary alteration. It is best identified by its distinct yellowish-brown hues and its occurrence within phosphate-rich zones alongside other rare minerals like triphylite.
Is this manganflurlite?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch manganflurlite with a known reference. Manganflurlite sits at Mohs 4-4.5, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Manganflurlite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Manganflurlite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: yellow, brownish-yellow, orange-brown.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: tabular crystals, massive.

Field-hunting tip
Look in granite pegmatites country, the host setting where manganflurlite typically forms. If you start seeing triphylite, phosphophyllite, strengite in float, you are in the right ground. Field specimens usually show a tabular crystals, massive habit, so train your eye for that shape before scanning the outcrop.
